' 12 Claims.

My invention relates particularly to a process of producing films having sound records and the product thereof, and applies particularly to goffered films adapted to be usedin the production 6 of colored motion pictures withsound.

The object of my invention is to provide a process, and, the product thereof, whereby films of the above character may be obtained. Previously the synchronization of sound with mo- 10 tion pictures has been accomplished in various ways. One way of accomplishing this has been by means of two independent synchronized films, one of-them carrying the sound record and the other the cinematographic image. Another 15 method has been the synchronization of a rotating photographicdisc with the film moving projecting mechanism. Such synchronization'has been substantially the same whether ordinary films or colored films of the goffered base have been used, but when attempting to apply the sound'record to a goflered film such as is used in the projection of colored motion pictures, diflicult problems arise. For instance, if the sound record is recorded on the gofiered base incidental sounds will arise on account of the periodic variations in the opaqueness due to the goflering. It is the object of my invention to overcome these difiiculties. While my invention is capable of being carriedout in many diiferent ways, and in connection with many difl'erent typesof apparatus, I have shown only certain types of apparatus which may be used in connection 'with my invention which Fig. 1 illustrates a portion of a film made in accordance with my invention; i Fig. 2 shows means by which the golfering may be removed on the portion of the film to 40' which the sound may be applied;

Fig. 3 is a diagrammatic representation of an apparatus which may be used in the preliminary gofiering of the film; and

Fig. 4 is a side elevation of an engraving cyl-- 45 inder which may be used in accordance with one embodiment of my invention.

In carrying out my invention a number of different modes of procedure may be followed but, generally speaking, I produce, in accordance with my invention, a gofiered film having a band thereon which is free from gofiering and which,

therefore, presents substantially the same properties therein as in the case of ordinary film' stock. A film of this kindmay be produced either by olfering the film in a band thereon,

in the accompanying drawing, in.-

that is, leaving a non-gofiered band, as, for ex-. ample, by using a cylinder 1 for the goffering which is engraved only at a portion thereof. Preferably, however, I proceed as follows in carrying out my invention: An engraved cylinder 5 2 will be provided in which the engraving thereon extends throughout the length of the cylinder or at least throughout a length greater than the width of a film 3 to be gofiered thereby. This is of importance inasmuch as it is found that the extreme edges of the engraving are always defective and do not provide the perfection which is desirable and which is readily obtained at the center of the engraving cylinder. For instance, in order to gofier a film of 35 mm. width one must have at least a 60 mm. width of engraving of which only the central band of 35 mm. is employed for the goifering of the film. Accordingly, after the film 3 has been thus goffered by feeding it between the engraving cylinder 2 and 0 the supporting cylinder 4, the film being accurately guided on both sides of the said cylinders, to prevent any right or left displacement thereof, by means of guides of any suitable type 5 and 6, a band 7 of the film will be subjected to a treatment for the removal of the goifering therefrom, thus leaving a'gofiered band '8 on which the colored motion pictures may be taken after the usual sensitized emulsion 9 has been applied to the other face thereof. These pictures so taken will be .taken and exhibited in synchronization with a sound record 10 applied to the non-gotfered band 7. The guiding of the film with great steadiness during the goifering is more easily accomplished because of they use of goffering in the form of transverse lines, as shown in the drawing (see application of Andre Oswald, Serial No. 307,601, filed September 22, 1928). Furthermore, it will'be understood that the said film may be copied in accordance with 40 the Keller-Dorian process and on the Keller- Dorian copying machine, so as to provide on similar films, in any desired way, the impression of the image to be produced in colors by projection, and that the sound thereon may be produced, if desired, by copying on the new film by contact with the film carrying the sound record. Also, it will be understood that the sound record may be produced on the original film in accordance with any desired system and in any desired way. However, it will be realized,

of course, that the Keller-Dorian copying machine used for copying the image from the goffered band of the film will be provided with the desired required'width by shutters, or otherwise 7o the entire widthof a filmby the gofierings of to accord with the widthof the gofiered band 8. The goifering may be removed from the band 7 as above referred to, in a number of different ways. For example, this may be accomplished by polishing the same with the aid of polishing and abrading materials, for instance, in any desired way, until the goffering is removed up to the pointwhere the image to be taken on the 'gofi'e'red band 8 begins. However, instead, the goffering corresponding to a bandsuch as the band 7 may be removed, if desired, from this portion of the film by applying to a. band 11 on a film 12 goffered in the sameway as the film 3, a composition 13 from a supply nozzle 14, such as to fill in and thus remove the get- .fering from the surface of the film at the band 11, this being'accomplished while the film is supportedupon and fed forward by a sprocket wheel 15. This composition 13 may either be comprised of collodion or a solution of gelatin, or a cellulose material such as that contained in the film 12 itself, dissolved in volatile solvents of any desired-character, or any other substance of same refractive a similar charactermay be usedto be applied to the film in this way, although, preferably, a composition is used having the'same' solid constituents asthe film itself, or at least having the index as the film. Such a film 12, having. the band 11, may then be utilized in the production of sound motion pictures the same as the film 3 with the band '7, above referred to.

Still another method of accomplishing this, where the film is goffered across its whole width, is to produce the sound record onanordinary non-goffered filmfo'f the appropriate width, that is to say, of a width similar to the width of the band '7 or the band'll, and then apply this to the gofiered face of the goffered film in a location similar to that of the band '1-or of the band 11, with the interposition of an adhesive composition, such, for example," as a collodion or solution of the film itself, above referred to, thus completely filling in goffering of the composite film at the band .where they are united together. This last menchanges may be made therein without depart-- ing from the spirit of the same,- asset forth in the claims.
